Definitions
- the invention relates to a method for controlling an electric parking brake of a commercial vehicle with an electronic control unit and a hand control unit which communicates with the electronic control unit, via which driver wishes are transmitted to the electronic control unit depending on the type of operation of the manual control unit.
- the invention has for its object to improve the ease of use of an electric parking brake.
- the invention builds on the state of the art in that the parking brake is closed due to an action performed by the driver of the utility vehicle, which is not related to the operation of the manual control unit.
- the driver to be relieved of his duty to operate the hand control unit while still engaging the parking brake.
- this facilitates the handling of the utility vehicle when the action taken is related to performing another action.
- the presence of a sufficiently low speed of the commercial vehicle is determined by comparing the wheel speed, the vehicle speed output of a control and the transmission speed with predetermined threshold values.
- the wheel speed can be determined directly by a sensor, the vehicle speed is generally considered Output value of a controller is available and it is for example entered into the CAN bus, and the transmission speed is supplied by the electronic transmission control and preferably also imprinted on the CAN bus.
- a preferred example of the usefulness of the present invention is that the action is to shift the shift lever of the gearshift to the parking position. Since the driver places the shift lever of the gearshift in the parking position anyway when the vehicle is parked, it is completely released from the active closing of the parking brake. This automatically closes when parking position is selected and the other conditions mentioned are present.
- the action is a special operation of the brake pedal. This is also useful since the engagement of the parking brake in the operation of the vehicle is often after braking the vehicle by pressing the brake pedal. Therefore, the driver's foot is already on the brake pedal, so that he can close the parking brake without effort by a special operation of the brake pedal.
- the special operation of the brake pedal comprises a persistence on the brake pedal when the commercial vehicle is already stationary over a predetermined minimum time interval.
- the special operation of the brake pedal after being held on the brake pedal when riding a commercial vehicle further passage of the brake pedal comprises.
- the further passage of the brake pedal can be detected via an increasing pressure in the service brake circuits. It is also possible to consider only one displacement sensor signal associated with the passage of the brake pedal.
- the present invention proves to be particularly advantageous in the context that, as an additional condition for the closing of the parking brake, a distance sensor detects measured values which are characteristic of a stop-and-go situation. Especially in stop-and-go operation, frequent closing of the parking brake may be desired. If the presence of such a stop-and-go situation is still considered plausible by measured values of a distance sensor, this can be used as a further criterion for the fact that the special operation of the brake pedal leads to the closing of the parking brake.

It discusses processes where certain effects (W01-W09) depend on certain conditions (B01-B30) and their logical association. Because of For reasons of clarity, these conditions and effects are listed below in a nutshell. A detailed description follows after this listing.

- B27 Switch 74 of the manual control unit is closed or signal WUP is present.
- B28 On-board diagnostics reports circular defect.
- EBC Electronic Brake Control
- WO1 Electric parking brake is closed according to predetermined time-pressure curve; Complete closing when the vehicle is stationary.
- W02 Electronic control unit activates solenoid valve for test function; Service brake assist if vehicle is moving.
- W03 Electric parking brake is opened.
- W04 Electric parking brake is closed.

- W06 Service brake pressure increases with low incline.
- W07 Service brake pressure increases with greater incline.
- W08 Electric parking brake is closed in accordance with specified time-pressure curve when service brake is activated.
- W09 Electronic control unit sends request to Electronic Brake Control (EBC) to execute a braking according to given time-pressure-characteristic.
- EBC Electronic Brake Control
- Figure 5 illustrates a normal parking operation using an electric parking brake.
- the electronic control unit checks the presence of the conditions BO1 to B07, logically links these conditions and, depending on the result of these connections, influences the electric parking brake. First, it is checked whether at least two of the conditions B01-B03 are present, that is, whether the wheel speed is below a predetermined speed, the vehicle speed is below a predetermined value and the transmission speed is below a certain value. If at least two of these criteria are present, a signal is output to the illustrated AND operation. In the case of this and other control operations described here, provision may also be made for the existence of one of the conditions to be sufficient. Further conditions to be checked are the presence of the condition B04, that is, whether the on-board diagnosis reporting error, and checking the condition B05, that is, whether the switch 70 of the manual control unit is closed or, in other words, whether the signal Sl is present.
- condition B06 the condition B06
- the electronic control unit is in its caster mode. If this test of the conditions BO1 to B07 leads to positive results on the assumption of the logical connections described, this has the effect WO1 on the electric parking brake; this is then closed according to a preset time-pressure curve; a complete closing takes place when the vehicle is stationary.
- the service brake pressure initially rises to a predetermined value p 2 until the time t 1. Subsequently, the pressure in the spring-loaded cylinders pF drops from a value pF1 to a value pF2 until the time t2, the value pF2 corresponding to a closed parking brake.
- This pressure curve which is simply shown here, may under certain circumstances have changed characteristics. For example, it is possible that, after the time t 1, the pressure pF in the spring-loaded cylinders initially drops slowly in accordance with a time-pressure curve and the vehicle is brought to a complete stop in front of the fully-loaded cylinder.
- Figure 6 shows a preferred variant of the insertion of the electric parking brake in a normal parking operation. According to FIG. 6, it is no longer absolutely necessary for condition B05, namely the closing of the switch 70 of the manual control unit, to be present. Rather, the electric parking brake can also be closed without further action by the driver when the selector lever of the gearshift of the vehicle is parked.
- FIG. 7 serves to test the parking brake in a utility vehicle equipped with a trailer. It is checked whether the commercial vehicle is able to keep the entire train independent when the parking brake is engaged. For a commercial vehicle parked on the mountain, this provides additional security.
- condition B09 is now checked, that is to say whether the parking brake is closed.
- the switch 80 of the manual control unit must be closed, in other words, the signal TEST must be present. If the logic operations come to a positive result, then the effect W02 occurs, that is to say the electronic control unit is activated the solenoid valve for the test function. Furthermore, assistance is provided by the service brake if the vehicle is moving.
- FIG 8 illustrates the normal release of the electric parking brake after the parking of the utility vehicle.
- the ignition must be switched on (B06), the switch 72 of the manual control unit must be closed, in other words, the signal Rl must be present (BIl), and optionally it can be checked whether the service brake is activated (B12).
- the condition B13 is met, that is, the engine is not running, the effect W03 can be triggered, namely the opening of the electric parking brake.
- the engine is running (B14)
- the signal R1 is not present when the switch 72 is open, the pressure in the spring-loaded cylinders pF remains at the level p2.
- the pressure in the Fe of the storage cylinders to the level pFl.
- the vehicle may start to move, as indicated by the arrow from t2.
- the conditions B19 and B20 can also be queried, namely whether an additional braking request is present and / or whether the distance to a vehicle in front is undershot in a manner characteristic of stop and go.
- the electric parking brake can be closed (W04).
- the pressure curve in the function diagrams illustrates this.
- the service brake pressure pB is initially increased to t1, wherein a tolerance range is indicated. If this service brake pressure subsequently remains over the period tl * and, furthermore, the brake pressure is subsequently increased to the pressure p2, the spring storage cylinders are automatically vented after the point in time t2 so that the parking brake is released at the time t2. is closing.
- FIG. 10 illustrates start-up during stop-and-go operation.
- the vehicle is starting to move or is starting to move (B21), whether the clutch and the drive train are closed with an allowable gear (B22), whether the Accelerator pedal requests an engine speed (B23) and whether a given engine torque has been reached (B24).
- the conditions B25 and B26 must be met simultaneously, that is, the vehicle was previously braked in stop-and-go operation and the ignition and the doors were not operated after the last braking operation, or it must be the already mentioned above condition BIO be present, that is, the switch 80 of the manual control unit must be closed, so that the signal TEST is present.
- the effect B05 then occurs, so that the electric parking brake is opened according to a predetermined time-pressure characteristic.
- the driver is thus enabled to release the parking brake during stop-and-go operation merely by triggering the TEST signal.
- the manual control unit is designed such that the actual release function (signal R1) can only be initiated with both hands, then the sufficiency of the signal TEST provides a considerable facilitation in the stop-and-release operation.
- the graph shows the rising engine torque M up to a value Ml at time tl and the subsequent venting of the spring-loaded cylinder from a pressure pF2 to a pressure pFl, so that after a time t2 the vehicle, indicated by can approach the outgoing from t2 arrow.
- FIG. 11 shows the conditions under which the commercial vehicle can be delayed by the electric parking brake. First of all, it must again be checked by checking the conditions BO1 to B03 already explained as to whether the vehicle is driving sufficiently slowly. Furthermore, according to condition B04, the on-board diagnosis must not report an error. If the condition B27 is initially present, that is to say the switch 74 of the manual control unit is closed, in other words, the signal WUP actually provided as the wake-up signal is present, then the service brake pressure can initially increase according to the effect W06 with a slight increase. This is shown in the diagram which plots the service brake pressure pB against the time t.
- the condition B05 can then be present, so that, according to the effect W07, the service brake pressure increases with a greater gradient until the time t1. Since, according to the condition B05, the signal S1 is present, a venting of the spring-loaded cylinders between the times t1 and t2 can subsequently ensue, which is shown by the pressure drop from pF1 to pF2.
- the pressure in the spring-loaded cylinders pF decreases according to the illustrated time-pressure curve. If there is no activation of the brake after the time t 1, the pressures show a reverse course.
- the on-board diagnosis must not signal an error (B04)
- the switch 70 of the manual control unit must be closed, in other words, the signal Sl must be present (B05), the ignition must be switched on (B06), the engine must run (B06) and the vehicle must move (B30).
- the electronic parking brake electronic control unit send a request to the electronic brake control (EBC) to perform braking according to a scheduled time-pressure characteristic. never sends (W09).
- EBC electronic brake control
- the brake pressure of the service brake increases to a pressure level p2; the pressure in the spring-loaded cylinders pF of the parking brake remains unchanged, that is, the parking brake remains open. If the switch 70 is opened at the time t 1, so that the signal S 1 is no longer present, the pressure in the service brake may drop again, so that the braking effect subsides and finally fails at time t 2.
